User Manual for ALP442e & ALP442e-MIC
9.2 Managing input and output levels
At the first installation of the card, the default gain settings are as follows:
Input analog gains are set to -24 dB (+24 dU -> 0 dBfs).
●
Digital input and output gains are set to 0 dB
●
The routing matrix is configured this way:
●
ALP442e & ALP442e-Mic
Play 1-2 routed to analog outputs 1-2
Play 3-4 routed to analog outputs 3-4
Play 5-6 routed to left & right channels of AES3 output 1
Play 7-8 routed to left & right channels of AES3 output 2
Analog Inputs 1-2 routed to Rec channels 1-2
Analog Inputs 3-4 routed to Rec channels 3-4
Left & right channels of AES3 Input 1 routed to Rec ch. 5-6
Left & right channels of AES3 Input 2 routed to Rec ch. 7-8
The other routing points of the matrix are muted (no mix).
Click on the
icon to access the "I/O Monitor" view which is used to adjust audio levels.
The onboard mixer features two categories of audio inputs and audio outputs
Physical inputs (analog and AES3)
●
Software playback inputs. They correspond to the playback devices exposed by the driver to
●
the applications.
Physical outputs (analog and AES3)
●
Software recording outputs. They correspond to the recording devices exposed by the driver
●
and captured by the applications
